To all whom it may concern:

Be it known that I, J GABRIEL Rncmmo, citizen of the Re ublic of Panama,residing at the city of anama, in the county of Panama and State ofPanama, have invented new and. useful Iin rovements in Aeroplanes, ofwhich the 0 lowing is a specification.

This invention relates to improvements in aeroplanes, and its object isto provide an aeroplane which embodies a plurality, preferably a pair,of superposed aeroplane units, each comprising a complete glidingstructure with its power plant, which units are rigidly-connected forconjoint operation to provide a double-decked machine, whereby greatspeed and radius of travel may be obtained, while'in the event of thestoppage of the power plant of either unit the power plant of the otherunit will maintain the machine in flight.

A further object of the invention is to provide a novel arrangementof'tlie superposed units whereby increased driving power and carryingcapacity, together with a reater stabi ity, will be obtained.

still further object of the invention is to provide a double-deckedaeroplane of thecharacter described in which the power plants 1 may beseparately controlled, while the steering elements "of the units willoper ate in unison for uniform control in steering and balanclngactions. 7

The inventlon consists of the features of construction, combination andarrangemepit of parts herein fully described andclain e reference beinghad to the accompanying drawings in which gear.

In carrying my invention into pr'actice,I

provide a pair of superposed aeroplane units 1 and 2, each of which iscomplete in itself with the exception of the use of launching andalighting gear upon the upper unit 2 the lower unit 1 being shown asprovide in the present instance with launching and alighting gear in theform of cushioned wheels 2 work, may be employed.

, but it is to'be'understood that any Specification of Letters Patent.Patented July 16, 1918,

Application filed-Hay 13, 1916. Serial No. 97,898.

suitable type of launching and alighting gear or any suitable type ofhydroplane surface, or a combination for land and water Each unit land 2disclosed in the present instance is of the monoplane type and comprisesa gliding structure composed of abody 3, which may beveither in the formof a fuselage or a naoelle, but which is shown in the present instanceas of nacelle type and provided with-a cock pit or compartment 4 for thereception of the pilot or aviator and passenger or passengers, if any.This part may be, and preferably is, of dream line form and is providedat the rear end of its tail portion with a combination vertical rudder 5and horizontal rudder or elevator 6.

The bodies 20f the respective aeroplane units are rigidly connected andheld in superposed relation by intervening connecting elements of anysuitable construction, which are herein shown in the form of a framing 7of suitable vertical bars, cross bars and reinforcing wiring. The unitsare coextensive in dimensions, but the lower unit preferably has itsforward end extended to a point sufficiently in advanceof the forwardend of the upper unit to provide free tractor propeller clearancewithout the necessity of spacing the units to an objectionable de gree.This arrangement also gives the machine two centers of gravity andpressure,

one in rear of the other, and a mean center of gravity and premure at apoint between the two, by means of which the balancing efiiciency orstability of the machine is greatly increased.

The supporting surface of each aeroplane unit consists as usual inlaterally extending wings 8,. which as set forth are of the monoplanetype, and may have any suitable lifting curvature. For the'purpose ofafl'ordin communication between the two cock pits o the machine, Ipreferably form a part of the framework 7 so that it provides a ladder9, for convenient ascent or descent, 'so, that in 1 the eventofdamage-to the power plant or controls of the Ulllt directly carryingthe e other pilot, he may pass therefrom to t unit in aquick and safemanner. Sets of control wires or cables 10 and- 11 lead from unison, sothat both horizontal rudders or both vertical rudders may besimultaneously erated from either of the cock pits or ilotscompartments.

Each unit is provided with its own power plant including a motor 14 anda tractor propeller 15, the propellers of the respectiye units beingarranged to operate one above and in rear of the other, so that properclearance will be obtained and any interference or workin resistance inthe operation of the propel ers avoided, The operation of the propellersin diflerent yertlcal planes provides for the lifting portions of theirthrust being at like distances from the centers of gravity and pressureof the re spective uints, by means of wh ch an eflicrent balance of themachine upon its supporting bank of air will be obtained. It will beevident from the foregoing de: scription that by providin the connectedunits, arranged as describe a machine of great speed and lifting poweris obtained, since multiplied driving ower will be ob tained. *Eorreasons state a machine ofsuperior stability is also roduced, and, asthe cock pit and other portlons of the body of one of the units may beemployed strictlyfor the carriage of fuel or su plies, the cruisingradius of the craft wil be greatlyincrease'd over the machine ofordinary construction.

Inasmuch as the steering gear of both units ifiay be controlled inunison, it willbe understood that the machine may be steered, balancedand maneuvered wit great ease and facility. Furthermore, in the event ofthe derangement of either power plant or set of steering controls, theremaining power plant or steerin controls may be employed to maintainflig t and stability. 'o

I claim:

1. A flying machine including a pair of rigidly connected, superposedaeroplane units, eachhaving its own power plant, a companion wayconnecting said units, and means for controlling and steering themachine from either unit.

2, A flying machine including a pair of rigidly connected superposedaeroplane units, each comprising a gliding structure units, eachcomprising a own power plant and steering gear, an duplicate controllingdevices u on. the respective units for operating sai steering gear.

5. A flying machine comprising a pair 'of rigidly connected units,eachhavin its own power plant and steerin gear, eac power plantincluding a forwari i tractor propeller, said units havlng their bowportions arranged one in rear of the other.

A flying machine comprising a pair of superposed aeroplane units, eachhaving a pilots compartment, a framing rigidly conhecting said units andincluding a companionway connecting said compartments, prollingmechanism upon each unit steering evices upon each unit, connected tormovement in unison, and controlling devices in the respective pilotscompartments for controlling said steering devices.

7:. A flying machine including apair of rigidly v connected, superposedaeroplane units, each having its own power plant, sets of steering andstabilizing devices upon the respective units, and means for controllingthe same from either unit.

8. A flying machine including a pair of rigidly connected superposedaeroplane liding structure of the monoplane type, and each having itsown power plant, steering and stabilizin elements upon the respectiveunits, and means for controlling the same from either unit.

In testimony whereof I, affix my signature in presence of two witnesses.
